Anotace
Overburden soils from open pit mines of the company RWE Power AG are excavated with bucket wheels and transported with band conveyors to dump heaps. The deposition of the waste soils takes place within so-called regular sections. In order to perform stability computations one needs a geotechnical characterization of the involved soils, and in particular representative values of shear stregth.Undrained shear strengths from laboratory and field testing are subjected to enormous scatter which makes the definition of the representative values difficult.
